Shenzhen Chaoyasi A17 Pro / A20PRO Bluetooth Earbuds

Troubleshooting: One Earbud Not Producing Sound

If one of your earbuds is not producing sound, follow these steps:

• First, ensure both earbuds are powered on.
• If both earbuds are powered on, the issue is likely due to the earbuds not being paired correctly.
• To resolve this:
  • Delete the pairing name of the earbuds from your phone's Bluetooth settings.
  • Place both earbuds back into the charging case, then remove them. The earbuds should automatically pair with each other.
  • During automatic pairing, one earbud may flash red and blue lights, while the other remains off. This is normal.
  • Once paired, select the device name on your phone to connect.
